\, Specification of Letters Patent.

Patented J'an. 1, 1907- Application filed October 13,1906. Serial'No.338,716.

To allfwhom it may concern: 7

Be it known that I, RAY-E. TIPTON, acitizen of'the United States,residing atAgra, in-

i forms-itsfhnctioil efficiently-and reliably,

which prevents the accessof trash, insects,

and other foreign matter to the filtering substance, and consequently tothe cistern, which canbe' easily andquickly cleaned; and whichconstruction. i

. With this general object in vi ew'and others,

as hereinafterappear, the invention consists in certain novel andpeculiar features of construction and organization as hereinafter de--scribed and'claimed, and in ord er'that-it'may be fully understoodreference is to be had to the accompanying drawings, in which Figure 1is a vertical section onthe line I Iof Fig. 3. Fig. 2 is a horizontalsection taken on the line II II of Fig. 1. Fig. 3 is a pprspective viewof the filter on'a reduced sca e.

In the said drawings, 1 indicates a rectangular base portion open at thetop and bottom by preference and provided with a front flange or cleat 2and side flanges or cleats 3. It is also provided with an opening 4 inthe back wall and with a hopper-shaped partition 5, which in practiceforms the actualbottom of the device and is equipped with a pipe 6,projecting outwardly through opening 4 and adapted for connection with apipe (not shown) leading to the cistern.

7 indicates the body portion of the device, the same being superposedwith respect to and secured upon base portion 1 and provided with a topor roof 8, equipped with an upwardly-projecting pipe 9, to be connecteddirectly or indirectly to the rain-spout. (Not shown.) U

The body portion is provided in the low er portion of its front wallwith an opening 10 and in the upper portion of its front wall with anopening 11, the first-named opening being for the admission and removalof a drawer 12, provided with a perforated bottom 13, said drawerresting upon the flanges or cleats 2 and 3. This drawer is adaptedpurpose of removing equivalent filtering substance;

14 indicates a shallow hopper partitioning thebody portionbetween'openings 110 an 11, the bottomof said: hopper: being pro-- videdwith depending-marginal angle-flanges 15, and removably" seated in saidhopperis of flanges 15' and in conjunction with the screen form ascreen-bottomed "receptacle to catchand retain small insects or otherfor-- eign particles, and said screen bottomedre- 'ceptacle is providedwith a hook or eye'18', whereby it may be conveniently removed afine-meshscreen 16, provided with walls 17, which project upward to theupperedges from the filter forcleansing of: other pur-- poses.

If the filter is of such size that ones hand cannot readily pass throughopening 11,a hook or other device (not shown) may be engagedwiththe hookor eye 18 for the the screenebottorned receptacle. i

19 indicates a coarse-meshscreen'parth tioning the bottom portion abovethe'hop per 14 and resting on" the side cleats 20 and front cleat 21,rigid with the bodyporition, said cleatsoccupying an inclinedplane:which'ispitched downwardly and forwardly. The front end of the coarsescreen extends through the opening 11 andisequipped with a cross-rod 22to fit down in the hooks 28, secured to the sides of the body portion inany suitable inanner, said hooks thus preventing any possibility offorward sliding movement of said screen and yetpermitting its front endto be lifted until the rod is disengaged from the hooks for the purposeof permitting the screen to be withdrawn from the filter. I

In order to protect the coarse screen from injury which might resultfrom the direct impact of the water and twigs and other foreignparticles therein, I. equip the rearend of the screen with a conicalplate 24, the same being located directly below pipe 9, and to relievethe screen pro er said plate is connected to the frame of said screen bya plurality of metal strips 25.

In practice as the water enters the filter it strikes and is distributedby the plate 24 the water and that portion of the foreign particles ofsufficiently minute size passing through the screen 19, while the twigsand other foreign particles too large to pass through the screen arecaused by the force of the water and the downward and forward in-.

to contain charcoal or anyother suitable Or IIO x 5 6 and thence to thecistern.

clination of said screen to travel forward thereon and eventually bedischarged through the ening 11. The Water and fine particles whic passthrough screen 19 fall into hopper 14, small insects and practically allparticles of suflicient size to be perceptible being retained in thescreen-bottomed receptacle '17, from which they can be removed in themanner hereinbefore explained. The'water I 0 after passing through thescreen 16 falls into the drawer containin the filtering substance and ispurified. It t en passes through the perforated bottom of the draweronto the ottom 5, from which it passes through pipe For the pur pose ofcleansing or renewing the purifying substance in the drawer the lattercan be quickly withdrawn through opening 10.

I Wish it to be understood that I do not de- 2o sire to be limited tothe exact details of construction shown and described, for obviousmodifications will occur to a person skilled in the art. I

Having thus described the invention, what I claim as new, anddesire tosecure by Letters Patent, is

1. A filter provided with an inlet-pipe and an opening in one of itswalls belowthe plane of the inlet-pipe, a screen within the filter be- 0low said pipe and projecting through said ppening, .and hooks secured tothe filter and engaging the front end of the screen to prevent thelatter slipping throiigh said opening.

2. A filter provided with an inlet-pipe and an opening in one of itswalls below the plane of the inlet-pipe, a screen within the filterbelow said pipe and projecting through said opening and provided with aplate to receive t e impact of the water entering the filter throughsaidpipe, and hooks secured to the filter and engaging the front end of thescreen to prevent the 'latterslipping through said opening.

3. A filter provided with an inlet-pipe and an opening in one of itswalls and occupying a lower plane than said tioning the filter andpitched downwardly and forwardly to the lower edge of said opening, ahopper within the filter below said screen and provided with a dependingangleflange wall, and a fine screen covering the opening of the hopperand provided with upwardly-projecting walls.

4.. A filter provided withan inlet-pipe in its roof near the uppermargin thereof, and a pipe, a screen partiequipped with ascreen-bottomed receptacle,

and means below the drawer to conduct water which passes through thelatter froin the filter.

In testimony whereof I afliX iny signature in the presence of twowitnesses.
